Bluetooth device shipments are forecast to grow 26 percent by 2023 (from 4 billion units in 2019 to 5.4 billion units). Silicon Labs designed the EFR32BG22 (BG22) SoCs to meet the unique requirements of high-volume, battery-powered Bluetooth products. Featuring an ultra-low transmit and receive power (3.6 mA TX at 0 dBm, 2.6 mA RX) and a high-performance, low-power M33 core (27 µA/MHz active, 1.2 µA sleep) – BG22 delivers industry-leading energy efficiency that can extend coin cell battery life beyond five years.

Automate:

The EFR32BG22C224 SoC provides IQ sampling and access to 125 kB and 500 kB Bluetooth LE Coded PHYs, which can increase RX sensitivity to -106.7 dBm. The SoC increases operating temperature to +125 ºC and extends flash memory up to 512 kB to support applications requiring direction finding capabilities or low-power mesh nodes.

Connect:

EFR32BG22C222 SoC targets applications requiring more compute power (with a 76.8 MHz M33 core), more I/Os (up to 26 GPIOs) and higher TX power (+6 dBm).

Locate:

The EFR32BG22C112 SoC targets high-volume, cost-sensitive applications such as asset tracking tags by eliminating the need for an external sleep crystal. These SoCs provide access to 1 Mbps and 2 Mbps Bluetooth PHYs, along with a 38.4 MHz Arm® Cortex®-M33 core, 18 GPIOs and 352 kB of flash memory with radio characteristics of 0 dBm transmit (TX) and an industry-leading -99 dBm receive (RX) (1M PHY) sensitivity.
